Abstract
An infrared imaging device enabling operation in the panning mode with a very high sensitivity and the facility of viewing a desired part of the observed field. A pyroelectric imaging tube is shifted relative to the observed scene and the infrared image on the target is read in a line by line scan the direction of the line being perpendicular to that in which the image is shifted. The shift takes place at a speed corresponding to a whole number R of line intervals in the course of one image frame scan comprising n=KR lines, with the result that each point is examined K times in the course of K successive frame periods; the video signal is accordingly processed to perform K successive integrations.
